AP Physics 1: Pivot Interactives Angular Motion
As students finished their torque quiz, I had them use Pivot Interactives to look at the motion of a spinning disk and come up with two different answers to which dot on a spinning disk is moving the fastest. Tomorrow, we’ll use those two answers to get into angular velocity vs. tangential velocity.
We spent some time whiteboarding yesterday’s problems. Students resisted drawing the diagrams for standing waves, but, once they got the diagrams, they were able to solve the problems.
Chemistry Essentials: Pivot Interactives Stoichiometry
Students used Pivot Interactives to compare their prediction for how much hydrogen gas should be produced in a reaction to how much was actually produced. I ran into an issue where a few students were very insistent that a prediction is a guess, so their calculation could not be a prediction. I didn’t have a great response in the moment aside from in science, a prediction should have something to back it up, which can be a calculation.
Another hurdle I ran into today is I have one section where a lot of students really resist talking to their group members, and the computers made it easier for them to work in isolation. As a result, I realized partway through the hour I was frequently answering the same questions multiple times with a given group and I was helping individual students with portions of the activity their partners knew how to do. I need think about how I can help my students have more productive collaboration within their group.
